INTRODUCTION
This manual is for the Endurance / Challenger
XL™ Modular Series Gas Ranges. Procedures in this
manual will apply to all models unless specified.
Pictures and illustrations will be of model 60SC unless
otherwise noted.
All of the information, illustrations and specifications
contained in this manual are based on the latest
product information available at the time of printing.
INSTALLATION, OPERATION AND
CLEANING
Refer to F38201 VULCAN ENDURANCE / WOLF
CHALLENGER Modular Series Gas Restaurant
Ranges I/O Manual for detailed installation, operation
and cleaning instructions.
LUBRICATION
Anderson and Forrester (or comparable) valve grease
for top burner gas valves, top burner pilot valves, and
pressure tap plugs. Apply light coat to valve/plug
threads. Valve grease must be insoluble in propane
and natural gas.
• A non perminate type sealer (preferably fast
drying) such as nail polish or equivelant for
sealing thermostat adjustment screw. If using
Loctite 242, it begins to set in approximately 10
minutes and fully cures in 24 hours according to
manufacturer.
• 3/4" pipe tee and hose barb assembly for
temporarily checking manifold pressure when a
pressure tap is not available in the gas manifold
on some models.
• Adaptor to test thermocouple closed circuit DC
voltages (purchase locally). Adaptors vary
between manufacturers. An example of one
adaptor type is pictured below.
Fig. 1
